I don't have a sub with the Blackhawk and de Capos and have never felt the need for one but my listening space is fairly small. There is some information about their frequency response in the Stereophile review but my affection for them is based on listening to them compared to other speakers I've owned in the same general price range from Merlin, Devore, Nola, ProAc and others.
I don't find it necessary to let the Blackhawk warm up before I begin listening but perhaps I'm not as analytical a listener as some.
